MC68HC908RF2 — Rev. 4.0
MOTOROLA
CHxF — Channel x Flag Bit
CHxIE — Channel x Interrupt Enable Bit
MSxB — Mode Select Bit B
MSxA — Mode Select Bit A
Register Name and Address: TSC0—$0025
Register Name and Address: TSC1—$0028
Figure 11-8. TIM Channel Status and Control Registers (TSC0 and TSC1)
When channel x is an input capture channel, this read/write bit is set when an
active edge occurs on the channel x pin. When channel x is an output compare
channel, CHxF is set when the value in the TIM counter registers matches the
value in the TIM channel x registers.
When TIM CPU interrupt requests are enabled (CHxIE = 1), clear CHxF by
reading TIM channel x status and control register with CHxF set and then writing
a 0 to CHxF. If another interrupt request occurs before the clearing sequence is
complete, then writing 0 to CHxF has no effect. Therefore, an interrupt request
cannot be lost due to inadvertent clearing of CHxF.
Reset clears the CHxF bit. Writing a 1 to CHxF has no effect.
This read/write bit enables TIM CPU interrupts on channel x.
Reset clears the CHxIE bit.
This read/write bit selects buffered output compare/PWM operation. MSxB
exists only in the TIM channel 0 and TIM channel 1 status and control registers.
Setting MS0B disables the TIM channel 1 status and control register. Reset
clears the MSxB bit.
When ELSxB:A ≠ 00, this read/write bit selects either input capture operation or
unbuffered output compare/PWM operation. See

1 = Input capture or output compare on channel x
0 = No input capture or output compare on channel x
1 = Channel x CPU interrupt requests enabled
0 = Channel x CPU interrupt requests disabled
1 = Buffered output compare/PWM operation enabled
0 = Buffered output compare/PWM operation disabled
1 = Unbuffered output compare/PWM operation
0 = Input capture operation
